              Hi, something changed within the past week or so on the vtk master branch, as of today when I build on linux with config RELEASE I get a build failure
/…/VTK/Common/DataModel/vtkSimpleCellTessellator.cxx:2529:5: error: “SLOW_API” is not defined [-Werror=undef]#if  SLOW_API
and a similar one in ThirdParty/doubleconversion/vtkdoubleconversion/double-conversion/doubleconversion.cc:532
and they go away if i define CMAKE_CXX_FLAGS -Wno-error=undef
Any clue what is causing this behavior?

              Hmm. The dashboards should have caught that. I added -Werror=undef recently to try and catch problems. I’ll have an MR up shortly.

              Thanks Ben, is this still waiting on merge request?

              Yes, I got all the instances of the flag causing failures that I hit on my machine on that MR, but there may be code I was not using and have instances still happening. Once that lands, master should be much better though.

              so far just one more
Rendering/OSPRay/vtkOSPRayPass.cxx lines 95 and 105
and vtkOSPRayWindowNode.cxx line 40 something…
and those two fixes gave me a clean build…
             
            
              
            
           
          
            
            
              Thanks for letting me know, this should clear that up:
